Hemolysis following wrap aortoplasty for Type A aortic dissection repair: Case report and review of the literature

Abstract: A Dacron wrap aortoplasty has been described as an adjunct to reduction ascending aortoplasty for the repair of Type A aortic dissections. We report a case of an uncomplicated hemiarch repair with wrap aortoplasty of the distal anastomosis which resulted in severe acute hemolysis. Despite only minimal focal graft deformation on imaging, the patient was found to have a flow gradient across the distal anastomosis, which was reduced by > 50% following release of the outer graft wrap. To our knowledge, only 29 add… Show more

“…Hemolytic anemia after central repair for acute aortic dissection has been attributed to outer compression of the graft, disturbance of blood flow at the site of obstruction, and a stenotic lumen within the graft. Davison et al [ 2 ] and Stanger et al [ 3 ] reported that graft stenosis is mainly due to the inversion of inner felt strips (50%) and not by kinking, as in our case [ 2 , 3 ]. In this case, we diagnosed hemolytic anemia due to graft kinking because no inner felt or artificial valve was used during the initial surgery.…”

“…Hori et al reported that Triplex showed the greatest increase in diameter among Hemashield, J-Graft, and Triplex after implantation compared to the package size within 43 months of surgery. In addition to reports of cases of flexion due to elongation of the grafts [ 2 , 9 12 ], Zierer et al reported enlargement of the residual aorta after the repair of acute type A aortic dissection, and this is suggested to be one of the reasons for kinked grafts [ 13 ]. However, the increase of the aortic graft length was not observed in our case, though it was not electrocardiogram synchronized (Fig.…”

“…A review of the literature revealed that the mean onset of hemolysis following aortic dissection repair was 32.2 months after surgery, with 16.7% of cases occurring within 2 weeks (2). When comparing mechanisms between acute-onset hemolysis (within 2 weeks postoperatively) and more delayed presentations, no cases of hemolytic anemia associated with graft kinking were identi ed in the acute presentation group (2). In this case, the computed tomography (CT) images immediately after the initial aortic dissection surgery showed mild exion of the graft, and there were no signs of hemolytic anemia at that time.…”

“…Reportedly, there were only 30 cases in which hemolytic anemia developed after aortic surgery in the English literature until 2018. 4 Although open surgery has been a treatment choice in most previous reports, it is not always feasible because of difficulties in accessing the kinked graft. 4 Herein, we describe a patient who presented with hemolytic anemia caused by graft kinking following ascending aortic replacement.…”
